Definitions
- This invention relates generally to a system and method for executing an aircraft circle-to-land maneuver, and more specifically to a system and method for executing a circle-to-land maneuver using the airborne area navigator.
- a circle-to-land (“CTL”) maneuver is one of the most challenging maneuvers required of flight crews.
- the CTL maneuver is used when an aircraft approaches an airport on an approach path that does not align with the favored runway.
- the CTL maneuver is not usually an issue because air traffic controllers at those airports can usually direct commercial aircraft to a straight in landing.
- a CTL maneuver becomes a more usual occurrence.
- a straight in landing may not be available and a CTL maneuver may be required, for example, because of inclement weather or traffic around the airport.
- a CTL maneuver is necessitated by limited air traffic control facilities.
- an airport may have a straight in instrument approach procedure, but local weather conditions or other constraints favor another runway that does not have such an approach. Under these conditions the initial approach to the airport may be straight in, but the flight crew must then resort to a CTL maneuver.
- navigational aids (“NAV AIDS") direct the aircraft to the center of the airport rather than to the end of the runway. The flight crew must then perform the CTL maneuver to align with the appropnate runway. 1 he pilot must use visual cues to " maneuver the aircraft to downwind, base and final. This maneuvering is done manually or by using limited automation available today from a flight guidance computer (“FGC").
- FGC flight guidance computer
- CTL maneuvers are performed at low altitude using visual cues such as runway lights.
- the CTL maneuver is very difficult in poor weather, at night time, or in other conditions of low visibility.
- the pilot is responsible for keeping the aircraft in protected air space. Landing an ai ⁇ lane, always a difficult task, becomes more difficult during a CTL maneuver because of the high work load experienced by the flight crew during the maneuver.
- a flight control system to control a circle-to-land (“CTL") maneuver of an aircraft.
- the flight control system makes use an airborne area navigator (herein referred to as "area navigator”) installed on the aircraft.
- the area navigator receives inputs on aircraft position and velocity, ai ⁇ ort navigation data, and pilot supplied data. In response to those inputs, the area navigator provides steering and other control commands to an onboard flight director.
- the area navigator also provides such commands to the aircraft pilot.
- the pilot has the option of executing the CTL maneuver manually using the provided information or allowing the aircraft autopilot to execute the maneuver under the control of the flight director.
- FIG. 1 schematically illustrates various landing situations giving rise to the need to execute a circle-to-land maneuver
- FIG. 2 schematically illustrates a circle-to-land maneuver
- FIG. 3 illustrates, in block diagram form, a circle-to-land system.
- ai ⁇ lanes including all commercial airliners, most business jets, and many private aircraft, have an airborne area navigator (herein referred to as an "area navigator") onboard the aircraft that aids in the navigation of the aircraft between ai ⁇ orts.
- area navigator an airborne area navigator
- the area navigator in combination with an autopilot system, can direct the flight of an aircraft from a time beginning shortly after takeoff and continuing until the aircraft approaches the destination ai ⁇ ort.
- the area navigator is an onboard computer that accepts data inputs from the flight crew, sensors, navigational aids ("NAV AIDS”) and air traffic controllers.
- NAV AIDS navigational aids
- the area navigator calculates a route between ai ⁇ orts and can either aid the pilot in flying from one ai ⁇ ort to another, or can be coupled to the autopilot to control the flight.
- the area navigator has the ability to calculate and control lateral navigation.
- more advanced area navigators have the ability to calculate and control vertical navigation.
- FIG. 1 illustrates various landing scenarios that may occur at an ai ⁇ ort 10 having a runway 12.
- an aircraft 14 would be directed to a straight in landing approach along the path indicated by arrow 16. This is the situation that is encountered, in most instances, when a commercial airliner lands at a large commercial ai ⁇ ort. Such a straight in landing is usually directed by the air traffic controller.
- aircraft 20 and aircraft 22 are directed along flight paths indicated by arrows 24 and 26, respectively, toward the center of the ai ⁇ ort 28. This may be the situation, for example, at smaller ai ⁇ orts where a straight in approach for a preferred runway is not possible.
- FIG. 2 illustrates the elements of a conventional CTL maneuver, again landing on a runway 12.
- the aircraft starting from a first waypoint 40, flies a downwind leg 42 to a second waypoint 44 in the direction indicated by the arrows.
- Waypoint 40 is located along a line positioned substantially at the end of and pe ⁇ endicular to runway 12.
- the flight crew then flies a base leg 46 to a third waypoint 48 and then a final leg 50 to a runway waypoint 52.
- Runway waypoint 52 is termed the "threshold” and waypoint 40 is termed to be "abeam" of the threshold.
- the pilot uses visual cues to aid him in the approach.
- the downwind, base, and final legs are executed manually by the pilot.- Especially in adverse weather conditions, at night, or in other poor visibility conditions, it is difficult to maintain the proper visual contact.
- PIC pilot in command
- the design, and optionally the execution, of the CTL maneuver is brought under the control of the onboard area navigator.
- the area navigator has the ability to control lateral navigation, and optionally to control vertical navigation, to date, the area navigator has not been programmed to design or fly CTL maneuvers.
- the area navigator is programmed to design and optionally to fly a CTL maneuver.
- the area navigator can be so programmed using conventional software programming. Upon being so programmed, the area navigator can provide steering and other control instructions or commands during the CTL maneuver.
- the flight crew would be responsible for getting the aircraft to waypoint 40 with or without the aid of the area navigator. From that location the area navigator could be used to design, and optionally to control, the CTL maneuver, both laterally and vertically. This would allow for a stabilized approach from waypoint 40 to waypoint 52 on runway 12.
- the following illustrates one embodiment of the invention.
- the area navigator provides pages of menus (on a visual display screen) to aid the flight crew in flying the aircraft. On one page, the ARRIVAL page, the pilot selects the runway to be used for landing.
- the pilot could choose runway 27 (i.e., a runway having a heading of 270 degrees) as the preferred runway and select a CTL maneuver to be performed to runway 27.
- runway 27 would correspond to the runway indicated by the numeral 12 in FIG. 2.
- the pilot could select, for example, VORDME 09, a final approach leg having a heading of 90 degrees.
- VORDME 09 indicates a navigational aid, Distance Measuring Equipment, corresponding to runway 09 (a runway having a heading of 90 degrees).
- the approach would be selected on the area navigator APPROACH page, The pilot could then select and indicate the intention to follow VORDME 09 APPROACH and that the CTL maneuver is being made to runway 27.
- the pilot or flight crew makes these selections from a menu provided by the area navigator.
- an APPROACH transition, STAR, and STAR transition could be selected at this point.
- the approach transitions are the preferred routes for the STAR to the initial approach fix that defines the start of the approach. "STAR" stands for Standard Terminal Arrival, and it defines the preferred route to be followed to the general vicinity of the ai ⁇ ort.
- the STAR transitions are the preferred routes from the enroute airspace structure to the STAR.
- the pilot at this time, could also input the aircraft category and minimum decent altitude ("MDA") into the area navigator. Alternatively, to reduce flight crew workload at this critical time, the aircraft category and MDA could be preloaded into the area navigator.
- MDA minimum decent altitude
- the aircraft category which is indicative of the type of aircraft and is determined by the aircraft approach speed, in turn, determines the protected air space for this particular type of aircraft. For example, the maximum indicated air speed for a category D aircraft is 165 knots. For this category, the protected airspace is defined to extend 2.3 nautical miles from the end of the runway. Knowing the aircraft category and the MDA, the area navigator is able to compute the protected air space for the aircraft and to compute the placement or location of the top of descent ("TOD").
- the TOD location is a dynamic factor that depends, for example, on the selected descent angle.
- the top of descent is the altitude at which the aircraft commences its constant descent to the runway.
- a menu page can be provided by the area navigator to allow for sizing of the CTL maneuver.
- Options available to the flight crew in sizing the CTL maneuver would include a choice of right or left turn direction, turn radius, final approach segment length, and final approach glide path angle.
- These factors in addition to the aircraft category and MDA, are supplied as inputs to and are used by the area navigator to calculate the appropriate CTL maneuver. Like the aircraft category and MDA, these factors can be preloaded into the area navigator to reduce flight crew workload during execution of the CTL maneuver.
- One advantage of the CTL system and method, in accordance with the invention is that pilots flying into unfamiliar ai ⁇ orts for the first time have the option to select the automated CTL maneuver and enter the traffic pattern altitude ("TPA") as the MDA. The area navigator can then be used to fly the traffic pattern.
- TPA traffic pattern altitude
- the advantage of this is that the aircraft would approach the runway on a stabilized approach while performing a 180 degree turn. The pilot would only need to monitor the system, allowing the flight crew the ability and luxury to look for other traffic in the traffic pattern.
- Another advantage of the CTL system and method, in accordance with the invention is that the area navigator is able to calculate and control the CTL maneuver to eliminate over shoots during the turn onto final.
- the area navigator is able to calculate a pre-defined ground track using its knowledge of aircraft conditions, together with winds or other atmosphere conditions, to anticipate the roll out onto final. This eliminates the possibility of the aircraft "flying through final” and getting too close to another aircraft making an approach on a parallel runway.
- the flight crew has the ability to modify the CTL maneuver in order to fly part or all of the CTL maneuver.
- the area navigator defines a ground track for the CTL maneuver.
- the flight crew can elect to fly directly to one of the waypoints associated with the CTL maneuver.
- the area navigator provides guidance to direct the aircraft to the chosen waypoint and then provides further guidance to direct the aircraft through the remainder of the CTL maneuver.
- the flight crew may be instructed to enter the traffic pattern on a base leg and not to fly a 180 degree turn.
- the flight crew could use the area navigator to modify the CTL maneuver to not fly abeam of the threshold, but instead to fly directly onto a base leg with a 90 degree turn onto final.
- the CTL maneuver can be modified to allow the aircraft to intercept any portion of the calculated CTL maneuver path.
- the area navigator provides guidance to turn the aircraft onto the correct path associated with the CTL maneuver.
- the area navigator would then provide guidance to the aircraft to complete the remainder of the CTL maneuver.
- the CTL maneuver can be modified to fly specific distances on final.
- VNAV vertical navigation
- the pilot sets an altitude preselector to "inform" the area navigator of the altitude to which it is desired to climb or descend. As the aircraft descends, for example, the pilot continues to dial the preselector to lower altitudes.
- the flight crew When flying an approach, the flight crew usually configures the aircraft for a missed approach prior to commencing the approach. This is done as a precautionary measure to reduce the workload on the flight crew if an actual miss should occur.
- One item in configuring the aircraft for a missed approach is to set the altitude preselector to the missed approach altitude. If a missed approach then becomes necessary, the flight crew can begin the missed approach climb, then engage VNAV, and the area navigator will control the climb to the preselected missed approach altitude.
- VNAV is placed in a mode (the Vertical Glidepath mode or "VGP") in which the VNAV ignores the preselector to cause the aircraft to descend lower than the preselector.
- VGP is only active during approaches. This allows the crew to dial the preselector to the missed approach altitude while the aircraft is descending without VNAV causing the aircraft to climb.
- the aircraft will level at the MDA while the preselector is set to the missed approach altitude. The aircraft will then fly at the MDA until the next TOD is encountered.
- the TOD will be encountered, in a CTL maneuver, at a location after waypoint 40 but prior to waypoint 52. At the TOD, the aircraft will begin to descend to waypoint 52 at the end of runway 12. All this will occur with the altitude preselector set for the missed approach altitude. If the pilot needs to execute a missed approach during the CTL, the preselector will already be preset and the aircraft will start climbing and will level off at the preselected altitude. This reduces crew workload during the missed approach and improves safety.
- FIG. 3 illustrates schematically a CTL system in accordance with one embodiment of the invention.
- the area navigator is adapted to receive inputs from several sources and, based on data from those sources, determining an appropriate CTL maneuver. Representative possible inputs are illustrated.
- sensor 64 provides position data
- sensor 66 provides aircraft velocity data
- sensors 68 provide data on atmospheric conditions.
- Another input of the area navigator receives ai ⁇ ort specific data 70 such as latitude and longitude of the runway and runway elevation.
- the area navigator is also configured to receive pilot entered information 72 such as a choice of left turn or right turn maneuver, turn radius, final approach length, approach velocity, and ai ⁇ lane category. Such pilot entered data can be entered on a real time basis or can be pre-entered.
- the area navigator also controls displays that provide information to the flight crew.
- a menu display 74 provides the ARRIVAL and APPROACH pages from which the pilot makes selections of desired runway, standard terminal arrival
- the area navigator also controls a display 76 that provides the flight crew with data on how to execute the CTL procedure such as appropriate headings, speed, and descent angle, and deviations in vertical and lateral position and deviation in approach speed.
- Display 76 can be, for example, in the form of a readout on a screen or in the form of an indicator on one or more dials or other types of cockpit displays.
- the area navigator makes the necessary calculations for defining the appropriate CTL maneuver and for controlling the aircraft during the CTL maneuver.
- Commands for controlling the aircraft in response to the calculations are conveyed to a flight director 78 if the aircraft is so equipped. These commands may include, for example, any of the following: a pitch command 80, vertical speed command 81, aircraft speed command 82, engine setting command 83, roll steering command 84, bank command 85, and the like.
- the aircraft may also include an autopilot 86 which, in accordance with one embodiment of the invention provides control surface commands 88 and engine throttle commands 90 to maintain the aircraft on the prescribed flight plan.
- An autopilot engage switch 92 under the control of the flight crew, determines whether the aircraft is flown by the autopilot 86 or under the manual control of the flight crew. If flown manually, the flight crew may receive input via display 76 or via flight director 78.
